D673H/F Pneumatic Hard Seal Clamp Butterfly Valve product details

D673H/F Pneumatic Hard Seal Clamp Butterfly Valve Product Overview
D673H/F Pneumatic Hard Seal Clamp Butterfly Valve produced and sold by Baigang Valve Group adopts precision J-shaped elastic sealing ring and three eccentric multi-level metal hard seal structure. It is widely used in metallurgical, electric power, petrochemical industry, water supply and drainage and municipal construction and other industrial pipelines with medium temperature ≤425℃, for regulating the flow rate and carrying the cutout body.The valve adopts three eccentric structure, the valve seat and the disc sealing surface are made of different hardness and stainless steel, with good corrosion resistance, long service life, the valve has a two-way sealing function, the product conforms to GB/T13927-92 valve pressure test standards.

D673H/F Pneumatic Hard Seal Clamp Butterfly Valve features
1, the valve adopts three eccentric seal structure, the valve seat and disc almost no wear, with the more the more tight sealing function.
2, the ring made of stainless steel, with the advantages of both metal seal and flexible seal, both in the case of low temperature and high temperature, have excellent sealing performance, with corrosion resistance, long service life and so on.
3, the butterfly plate sealing surface using welding cobalt-based hard alloy, sealing surface wear-resistant, long service life.
4, Large-format butterfly plate frame structure, high strength, large flow area, small flow resistance.
5, the valve has a two-way sealing function, the installation is not subject to restrictions on the flow of media, but also the location of space, can be installed in any direction.
6, the drive can be multi-station (rotated 90 ° or 180 °) installation, user-friendly.

D673H/F Pneumatic Hard Seal Clamp Butterfly Valve principle
Electromagnetic valve to control the pneumatic actuator, the valve stem to achieve the purpose of turning 90 °.

Cylinder with 1/4 rotary cylinder, adjustable angle 1 ° ~ 5 °.
